Dear all,
I have run RegCM4.0 with the same regcm.in file, which is attached in this email, for 8 years. Even though there was no problem with the years 2001, 2002, 2003, 2004, 2005, 2006, 2007 when I ran it for the year 2000, I saw the message below at the terminal:
70E-05 0.42932E-07, no. of points w/convection = 1137
*** solar declination angle = 19.60 degrees.
dectim = 486720.00000000000
OUT-history written date = 2000072406.0000000
LAND variables written at 2000072406 0.0000000000000000
Writing rad fields at ktau = 121320 2000072406
BCs are ready from 2000072406 to 2000072412

CFL VIOLATION

Aborted
How is this explained? The only things I changed each time were the ICBCs and the year in the regcm.in file.
